Many high power applications require a high level of accuracy :
- A precise control of beam pattern distribution is essential to precisely control the location of the ultrasonic beam and its interaction with tissue
- A precise control of the amount of generated power is necessary to control the effect itself
The consequences of the inapropriate use of the high power transducers can be serious as unexpected lesions of human tissues.
Moreover, the right functioning of a high power transducer also depends on operating conditions. For example :
- Excess of electrical power or inapropriate cooling may damage the transducer and produce various uncontrolled effects.
- Inappropriate electrical matching may produce unexpected level of reflected electrical power and can produce spurious effects on the electronic circuits.
